Frontal horn width to intercaudate distance ratio (FH/CC)

Case contributed by A.Prof Frank Gaillard

Case Discussion

Diagram demonstrating how to measure:

  • frontal horn width 
  • intercaudate distance
  • inner table width

FH/CC ratio :normal mean 2.2 to 2.6 (this ratio decreases with ageing as a result of enlargement of the frontal horns of the lateral ventricles). 

CC/IT ratio : normal mean 0.09 to 0.12
